Dasiphora plant named ‘LISSDAN’

ABSTRACT

A new cultivar of  Dasiphora , ‘LISSDAN’, that is characterized by its upright, bushy plant form, its single flowers with the upper surface of the petals bright cerise to fuchsia pink in color and the lower surface of the petals pale cream to parchment in color, and its flowers that retain their color throughout the blooming season.

Botanical classification: Dasiphora fruticosa subsp. fruiticosa.

Variety denomination: ‘LISSDAN’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofDasiphora fruticosa subsp. fruiticosa (syn. Potentilla fruticosa). Thenew cultivar will be referred to hereafter by its cultivar name,‘LISSDAN’. ‘LISSDAN’ is a new cultivar of deciduous shrub grown forlandscape use.

‘LISSDAN’ was discovered by the Inventor as a chance seedling in hisgarden in Eccleshall, Stafford, United Kingdom in 2007. The parentage isunknown.

Asexual propagation of the new cultivar was first accomplished bysoftwood cuttings under the direction of the Inventor in Greatham,Hampshire, The United Kingdom in spring of 2008. Asexual propagation bysoftwood cuttings has determined that the characteristics of the newcultivar are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent thecharacteristics of the new shrub rose. These attributes in combinationdistinguish ‘LISSDAN’ as a unique cultivar of Dasiphora.

-   -   1. ‘LISSDAN’ exhibits an upright and bushy plant habit.    -   2. ‘LISSDAN’ exhibits single flowers with the upper surface of        the petals bright cerise to fuchsia pink in color and the lower        surface of the petals pale cream to parchment in color.    -   3. ‘LISSDAN’ is exhibits flowers that retain their coloration        late in the blooming season.

‘LISSDAN’ can be most closely compared to the Dasiphora cultivars‘Marrob’ (not patented) and ‘Red Ace’ (U.S. Plant Pat. No. 4,226).‘Marrob’ differs from ‘LISSDAN’ in having an irregular, lax and lessupright plant habit, in having flowers with petals that are orange-redin color and fade to a dull orange on the upper surface and pale greento beige in color on the lower surface. ‘Red Ace’ differs from ‘LISSDAN’in having a less upright and lax plant habit, in having flowers withpetals that are less pink in color and fade to a dull orange on theupper surface and pale green to beige in color on the lower surface.
